Tutorial 2 ELM Images File Selector and Popups

 #Creates an Image object that displays an image
 ic = elementary.Image(window)

 #Use the os module to get the current path to our .py file. Our image is relative to our .py We do this because it is best to use the absolute file path to images for the best results.

 #Tell our icon to auto-fill open space
 ic.size_hint_weight_set(evas.EVAS_HINT_EXPAND, evas.EVAS_HINT_EXPAND)

 #Here we set the image we want our icon to display
 ic.file_set("%s/images/logo.png"%location)

 #Optional, lets add mouse over text to our image
 ic.tooltip_text_set("Look a pretty picture!")

 #Lets show our icon
 ic.show()

 box.pack_end(windytax)
 #Pack our icon between our text and button
 box.pack_end(ic)
 box.pack_end(button)

 #Creates a "FileselectorButton" object. This is a button (just like we have created before) except that when it is click it automatically opens a file selector window
 fsb = elementary.FileselectorButton(window)

 #We can set the text of our fsb just like a normal button text
 fsb.text = "Change Image"

 #Tooltip for mouse over
 fsb.tooltip_text_set("Click Me!")

 #This tells our file selector window what to do when our user selects a file. The first argument is the callback function we want run and our second argument is our image object we want to change the display of
 fsb.callback_file_chosen_add(change_image, ic)

 #Show our button
 fsb.show()

 box.pack_end(windytax)

 window.show()

#Our fileselector callback. The file argument is the fileselectbutton object. The second argument is the full path to the file that was selected. The final argument is the image object we passed to this callback
def change_image(fsb, file_selected, image):
 #Check to make sure a file of some sort was selected. If nothing was selected file_selected will equal None type
 if file_selected:
 #These are the extensions we will allow our program to display

 #If the extension is in our validExtenions lets check the image we are displaying!
 if fileExtension in validExtensions:
 image.file_set(file_selected)

#This time we also pass the window object to our change image function. The reason for this is that our popup object needs a parent window object
def change_image(fsb, file_selected, image, window):
 if file_selected:
 validExtensions = [".png", ".jpg", ".gif"]

 fileName, fileExtension = os.path.splitext(file_selected)

 if fileExtension in validExtensions:

 else:
 #if we have an invalid extension lets give the user a popup message telling them why the image didnt change

 #Create a popup message
 popup = elementary.Popup(window)

 #Set the title of our popup
 popup.part_text_set("title,text", "Invalid File Extension")

 #Set the text of our popup
 popup.text = "File %s has an invalid file extension of %s"%(fileName, fileExtension)

 #Create a button object
 bt = elementary.Button(window)

 #Set its text
 bt.text = "OK"

 #Define a callback that is called when the button is clicked, lets pass our popup object to this call back so we can close the popup when the user presses OK
 bt.callback_clicked_add(bnt_close, popup)

 #Sets content for our popup. The first argument is an arbitrary name for the content piece and the second argument is the elementary object you would like displayed for the content
 popup.part_content_set("button1", bt)

 #Show the popup to our user
 popup.show()

#The callback for our popups OK button. The first agurment is the button object itself and the second object is the popup we passed to it

Tutorial Cara Instalasi File apk ke Smartphone Android

Android adalah OS yang paling banyak di gunakan di dunia smartphone saat ini. Nah, di sini Jerukers dapat mengetahui cara termudah untuk meng-install file ".apk" ke dalam smartphone berbasis Android yang digunakan.

Android Application Package adalah kepanjangan dari file dengan extention .apk, dimana fungsinya mirip dengan ekstensi .exe yang digunakan untuk intalasi file ke dalam operating system Windows. File .apk digunakan untuk melakukan instalasi di operating system Google yaitu Android, di mana pada saat ini adalah OS yang paling banyak digunakan di smartphone.

Salah satu alasan mengapa Android bisa menjadi OS mobile yang paling banyak digunakan pada saat ini adalah karena Android merupakan operating system yang bersifat open source, dalam artian bahwa Google memberikan kebebasan kepada para developer untuk membuat aplikasi buat digunakan di smartphone yang berbasis Android.

Supaya para developer aplikasi bisa mendapatkan penghasilan dari aplikasi-aplikasi yang mereka develop, maka mereka harus mendaftarkan aplikasi tersebut ke Play Store. Namun tanpa masuk ke dalam Play Store pun para developer sudah dapat menyebarkan aplikasi mereka misalkan untuk keperluan testing atau malah hanya digunakan untuk keperluan internal saja.

Cara untuk instalasi file .apk sangatlah mudah. Namun sebelumnya, Jerukers harus mengubah settingan di Android untuk dapat menerima file .apk di luar dari Play Store. Caranya adalah ke Setting, lalu masuk ke Security. Scroll ke bagian bawah, di bagian Device Administration ada tick-box untuk "Unknown Source". Nantinya, akan keluar kotak notifikasi yang menyatakan bahwa Jerukers sendiri yang akan bertanggung jawab atas segala hal yang di akibatkan oleh aplikasi yang bukan di install melalu Play Store, klik OK.

Lalu copy file .apk yang ingin di-install ke Android kamu ke dalam memory card. File yang ingin di-install itu harus dengan extention ".apk, sebagai contoh di sini kami menggunakan aplikasi "MyTable.apk" yang sudah di-copy ke dalam external memory card micro SD. Lalu selanjutnya tinggal mencari file tersebut menggunakan file explorer yang ada di dalam Android.

Apabila di smartphone kamu belum ada aplikasi file explorer, salah satu aplikasi file explorer terbaik yang direkomendasikan oleh tim JerukNipis adalah Astro File Explorer, bisa didapatkan melalui Android Play Store secara gratis. Setelah ketemu file .apk yang ingin di-install, tinggal klik file tersebut dan ikuti langkah-langkah berikutnya seperti contoh yang terlampir:

Setelah di-klik, akan ada notifikasi persetujuan bahwa aplikasi ini akan memiliki akses terhadap apa saja di Android kamu, klik Install:

Jika aplikasi sudah sukses ter-install, maka indikasinya bisa dilihat sebagai berikut:

Transfer Bulk Data via Torrent file

Hi Friends, 

This article is all about the Torrent File Transfer Mechanism and its features. How to optimize Torrent client and how to create our own Torrent file for transferring bulk data instead downloading Movies and Software from other Torrent sites.

What is Torrent?

Torrent is the protocol for distributing files. It uses Peer-to-Peer data transmission. Its advantage over plain HTTP is that when multiple downloads of the same file happen concurrently, the downloaders upload to each other, making it possible for the file source to support very large numbers of downloaders, with only a modest increase in its load.Torrents peer protocol can operate over TCP or uTP.

Torrent is created by Bram cohen in 2001 and now handled by BitTorrent.inc company

Torrent file distribution consists of these entities:

• An ordinary web server
• A static metainfo file
• A Torrent tracker
• An original downloader
• The end user web browsers
• The end user downloaders

Torrent Files

Torrent files are also known as metainfo files which are bencoded dictionaries which contains metadata like name, piece length, pieces, length, path and announce URL for trackers

Trackers

Tracker GET requests have the following keys:

• info_hash- Bencoded form of info values
• peer_id-Random generated id at the start of new download
• ip-Trackers machines IP address
• port-Port number for listening on peer
• uploaded-Total amount uploaded so far
• downloaded- Total amount downloaded so for
• left-Remaining amount has to download
• event-Announcement events such as started, completed, stopped(empty)

How Torrent Network works?

Seed is the user or computer that has a file can be downloaded. There are also so-called leechers/peers. Leechers are the users or computers who want to download the file. When one leecher has managed to download the files 100% of the seed, then the leechers role will change to seed. Therefore torrent source files are not fixated on single sources. 

Advantage of Torrent

• It will be very faster when the files are being download by many users. But normal download will fail s to serve if number of downloaders increases.
• By downloading via torrent, the same file can be downloaded from many sources.
• The leecher can become seeder once the download complete to serve other leecher.
• It consume less CPU utilization compared to normal download.
• It allows to transfer files with anyone, anywhere. 

Tips to optimize Torrent Client[Some Popular Torrent Client Softwares are BitTorrent, uTorrent, Vuze, qBittorrent.]

• Go to Options-> setup guide -> uncheck the bandwith 
• Go to Options-> Preferences -> Advanced -> Change "net.max_halfopen" value to 50 by selecting the line, modifying the value at the bottom to 50 and clicking Set.
• At the same Advanced screen, Change "bt.transp_disposition" value to 255 by selecting the line, modifying the value at the bottom to 255 and clicking Set.
• More Peers means more speed, To get more peers, right-click the entry on the list of peers , and click Update Tracker.
• Increase the number of connections by Options -> Preferences -> Bandwidth -> Number of Connections. Experiment by increasing the number of global/max connections in steps of 25
• Increase the speed of particular torrent by setting the download limit to unlimited and upload limit to very less.

How to transfer files via Torrent file.

Step 1: Create Built-in Tracker

        a) Open the utorrent Software->Options->Preferences

        b) Go to Connections and set the port number which is opened/unused

        c) Then go to BitTorrent and set the IP/Hostname to report to tracker: [as your sender IP address]

        d) And go the Advanced and set true for bt.enable_tracker and save the setting

Step 2:Create Torrent file

        a) Click File->Create New Torrent

        b) Select Source which you want to transfer

        c) Give the Torrent Properties Tracker values as "http://[Sender IP Address][Port]/announce"   

        where  Port and Sender IP Address are we already configured in tracker

        d) Delete if any other trackers found other than our tracker.

        e) Give tick Start Seeding and Private torrent. and press Create

Now this will create a .torrent extension file

Step 3:Download the file from any other system like as normal as we download movies using .torrent file.
